Study Summary

The hip prosthesis market is constantly growing with the number of prostheses reaching 949,000 in 2019. Along with this, there is also an increase in interest in short stems also called shortened stems. Thus on Pubmed, in 5 years, 171 publications have been listed.

Thus, it seems interesting to study and analyze the performance of the shortened stem used in the Department of Orthopedic Surgery and Traumatology of the University Hospitals of Strasbourg and to compare them with the results of the literature.
